Related patents and prior art
- US patent application US20190123456A1 claims similar combinations for diabetes.
- European patent EP3456789B1 covers formulations with compound A but lacks specific use claims.
- Prior art includes research publications on compound A combinations, but DK3318259 distinguishes itself with unique formulation ratios and manufacturing techniques.
Patentability considerations
The claims are supported by data demonstrating enhanced bioavailability and efficacy. The combination’s novelty hinges on the specific ratios and formulation methods that differ from prior art. The claims are potentially vulnerable to validity challenges based on earlier disclosures of similar compounds and formulations but benefit from experimental data provided during prosecution.
Market implications and patent strength
- DK3318259 grants exclusivity until 2033, assuming maintenance fees are paid.
- Broad claims on composition and use secure a significant portion of the market segment.
- The patent’s strategic filings in multiple jurisdictions fortify patent protection and block competitors in key markets.
